Learning unit contents
Description of the teaching:
The general chemistry course is largelybased on an experimental approach. We are convinced that students will be more receptive to a chemistry described in a practical way, with a focus on the applications linked to the explored topics.
Table of contents:
Chapter 1: Matter and Atoms, Reminders
1.A Introduction: structure of the atom, isotopes, law of conservation of the matter.
1.B Periodicity of the elements.
1.C Key concepts: atomic and molecular masses, mole, molar mass and volume.
Chapter 2: Atoms and Electrons
2.A Light: electromagnetic wave, absorption spectroscopy, atomic emission, photoelectric effect.
2.B Atomic structure: planetary model of Bohr, wave-particle duality, ondulatory mechanics, model of the atom according to Schrödinger, quantum numbers and atomic orbitals.
2.C Electronic configuration of elements: spin quantum number, Pauli exclusion, Klechkowski and Hund rules.
Chapter 3: Molecules and Complexes
3.A Chemical binding: introduction and reminders
3.B Theory of the valence and of the molecular orbitals: chemical bond, LCAO model, electronegativity, electric dipole and dipolar moment.

3.D Weak energy bonds: Van der Walls forces and hydrogen bonding.
Chapter 4A: Thermochemistry and 1st Principle of Thermodynamics
4A.A Introduction to thermodynamics: definitions and tools.

Learning outcomes of the learning unit
General chemistry teaching during the second period of the year aims to give to the students the basic theoretical and practical concepts in molecular chemistry, thermodynamics, kinetics, and solution chemistry (reactivity). These concepts are necessary in order to understand the phenomena studied in later parts of the curriculum.
Theoretical classes, practical work and tutorials allow students to learn the methods and basic techniques of solution chemistry while familiarising them with the formulae of the chemical products and understanding their evolution by change of phase or reaction. A special focus will be given to the chemical equilibrium conditions.
Prerequisite knowledge and skills
For the entire course, the student is assumed to have very basic understanding of chemistry and in particular, to have knowledge of the basics of atomic and molecular theory as well as the elemental properties of the main types of chemical compounds (oxides, acids, bases and salts) and their principal reactions. These concepts will, however, be revised early on in the course. This course also makes use of a range of simple physical and mathematical tools.
Planned learning activities and teaching methods
In addition to theoretical courses and sessions of exercices organized according to the established schedule, supervised laboratory work sessions will also enrich the teaching.
Organization. Practical lab sessions will be scheduled throughout the academic year. They will illustrate the important notions of reactivity in solution. A calendar will be distributed to students at the beginning of the year.
Security. Wearing the lab coat and glasses is mandatory. Any student who does not have his equipment will be excluded from the laboratory, and will automatically be sanctioned with a 00/20 at the session.
Attendance at practical sessions. TP sessions are mandatory and rated. An unjustified absence (eg medical certificate) will automatically be sanctioned by a 00/20 at the meeting.
Mode of delivery (face-to-face ; distance-learning)
Each student will receive a personalised programme (log book) at the start of the year summarising all the information relating to the organisation of chemistry teaching (theory classes, practical sessions, revision, tutorials, tests).
An interactive online teaching platform is also available on eCampus, and offers to the students various learning tools such as course materials, TP and TD notes, solved problems or again a forum for asking questions.
Recommended or required readings
Leture notes and copies of the illustrations (pdf) will be available online following the course completion.
Assessment methods and criteria
Organization of exams.
An exam will be organized in May-June (first session), under the form of multiple choice questions combining both theoretical questions and exercises.
For students who have failed at the first session, a second exam will be prepared in May-September (second session).
Weighting of the notes:
The final grade of chemistry will be weighted like this:
Exam: 75%
Laboratories: 25%
Success criterion:
Success is awarded to any student with a final score equal to or greater than 10.00 / 20.
Work placement(s)
Organizational remarks
Lecture notes and illustrations will be available online (myulg) after each lesson.

Adaptation of teaching commitments following the COVID-19 pandemic for the May-June 2020 session
Teaching methods implemented : distance-learning
The end of the theoretical course will be provided as podcasted videos. Each video containing from 30min to 1h of theory, will be progressively posted according to the advancement of the course. The exercise sessions will also be podcasted with the help of Camdocs and progressively posted onto the ULiege website.
The students will also have access to all the slides in pdf for the theory and the exercise sessions, classically deposited on e-Campus.
All the team will be available for answering any question, through a dedicated forum on eCampus.
Questions will never be treated by email.
Assessment subjects
The final evaluation will concern all the chemistry, taught in face-to-face as well as podcasted, whatever during theoretical lesson or exercise sessions.
Assessment methods
The exam will be proposed on-line (e-Campus) through the mean of multiple choice questions, covering the full chemistry studied in theory and during the sessions of exercises. The total duration of the exam will not exceed 2h.
This exam will represent 75% of the global score, which will be completed by the score corresponding to the practical work in laboratories (25%).
Please note that a computer as well as a stable internet connection will be requested to participate in the exam in the best conditions.
